Google PCA Designing for Security and Compliance Practice Question
A company has a VPC Service Perimeter that protects a project containing BigQuery datasets. They want to allow an external customer's BigQuery job to query data across the perimeter boundary using a private connection. Which configuration is required?
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Create an ingress rule in the service perimeter that allows access from the external customer's VPC network.
To allow access from outside the perimeter, you can use VPC Service Controls with ingress rules. Additionally, the external customer must use a private connection, such as Cloud VPN or Dedicated Interconnect, to access the perimeter. The ingress rule specifies the source and resources.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Remove the project from the service perimeter temporarily.
Why it's wrong here
This would defeat the purpose of the perimeter.
- ✓
Create an ingress rule in the service perimeter that allows access from the external customer's VPC network.
Why this is correct
Ingress rules allow traffic from specified sources into the perimeter.
- ✗
Use Access Transparency to log cross-perimeter access.
Why it's wrong here
Access Transparency provides logs, not access.
- ✗
Grant the external customer's service account the BigQuery User role.
Why it's wrong here
IAM alone does not bypass VPC Service Controls.
